Abstract:
The anti-reflective cracking fatigue life of asphalt course and the fatigue strength of concrete slab were taken as design basis. The structure design methods of the specifications for the cement concrete pavements of civil transport airport and highway were analyzed. The calculated equations of load stress, temperature stress and anti-reflective cracking fatigue life were studied. A structure design method of composition airfield pavement was put forward. Its two design indexes were the synthetic fatigue stress under load and temperature for concrete slab and the fatigue life of anti-reflective cracking for asphalt surface course. During the analysis of design examples, the projects of single layer, double layers and three layers were contrasted. The result indicates that for double layers modified asphalt structure, the fatigue stress is 4.84 MPa, and the anti-reflective cracking fatigue life is 699 362 times, which meets the design requirement of the example, so the project is credible and the structure design method is reasonable. 6 tabs, 1 fig, 10 refs.
